LETTER-PRESS-COPYING CLOTH AND FRAME.

SPECIFICATION forming part of Letters Patent No. 707,7 53, dated August 26, 1902.

Application filed December 4, 1901. $erial No. 84,597. (No model.)

The end edges of this cloth of the apertures of the respective series may 50 are secured to the projecting arms 7 in such be brought into alinement or registration by manner that the cloth will be stretched and sliding the sections upon each other. The

apertures 10 of the sections 6 are plain or unthreaded, while the apertures 10 of sections 6 are threaded. (See Fig. 5.) A small screw 11 is adapted to be passed through the registering apertures, the extremity only of said screw being threaded so as to engage with the threads of the aperture 10. In order to form guides for the sliding of one section of the main member upon the other, Iprefer that the end of each of said sections shall be split and spread out laterally and thence bent around and beneath the other section, as indicated by the numerals 12 12.

While the above-described construction for adjustably holding the sections of the main member together is the preferred means, yet I do not wish to be understood as limiting myself specifically thereto, inasmuch as it is obvious that any other desirable construction for holding said sections adjustably together may be employed without departing from the spirit and scope of my invention. By providing for this adjustment it is obvious that the length of the frame can be readily adjusted so as to suit different sizes of letterpress books, and all that will be necessary will be to have on hand a supply of different lengths of the cloth. This adjustable feature may also be found useful merely for the purpose of placing the cloth under additional tension or stretching if from any cause said cloth may sag or become loose.

What I claim as my invention is- 1. In a letter-press-copying cloth and frame, the combination with a copying-cloth, of a frame comprising a main member and two arms extending in the same direction and at angles from opposite ends of the main member, said arms having the opposite end edges of the cloth secured thereto, and the cloth drawn tight thereby, the length of the arms ber, said arms having the opposite end edges of the cloth removably secured thereto and the cloth drawn tight thereby, the length of the arms being such that the main member will lie parallel with and outside of the outer side edges of the leaves of the copying-press book, when the device is applied between said leaves, and the distance apart of the arms being such that said arms will lie parallel with and outside of the opposite end edges of the leaves of the book.

3. In aletter-press-copying cloth and frame, the combination with a copying-cloth having its opposite end edges provided with loops, of a frame comprising a main member and two arms extending in the same direction and at angles from opposite ends of the main member, said arms adapted to have the end loops of the cloth removably fitted thereon and the cloth drawn tight thereby, the length of the arms being such that the main member will lie parallel with and outside of the outer side edges of the leaves of the copying-press book, when the device is applied between said leaves, and the distance apart of the arms.

being such that said arms will lie parallel with and outside of the end edges of the leaves of the book.

4. In aletter-press-copying cloth and frame, the combination of a frame comprising a main member consisting of two sections extensibly fitted together, and each section having an arm extending therefrom at an angle, means for holding the sections of the main member in adjusted position, and a copying-cloth secured at opposite end edges of the arms.

5. Inaletter-press-copyingcloth and frame, the combination of a frame comprising a main member consisting of two sections slidably fitted together, and each section provided with apertures, any two of which may be brought into registration, and each section also provided with an arm extending at an angle therefrom, a pin adapted to be fitted in the registering apertures to thereby hold the sections in adjusted position, and a copying-cloth secured at opposite end edges to the arm.

In testimony whereof I affix my signature in presence of two witnesses.
